Description

Technical Field

[0001] This invention relates to the field of frame welding positioning technology, and in particular to a welding equipment for electrical control cabinet frames. Background Technology

[0002] An electrical control cabinet is a device used to assemble electrical components such as switching equipment, measuring instruments, protective electrical equipment, and auxiliary equipment into a closed or semi-closed cavity according to the wiring requirements of electrical components. It is widely used in the field of industrial power supply. As a core device in industrial automation and power systems, the welding quality of the frame of the electrical control cabinet directly affects the structural strength, sealing performance, and safety of the cabinet. In order to ensure the welding quality of the electrical control cabinet frame, specialized welding equipment is required for the auxiliary fixing of the metal frame poles.

[0003] For example, the Chinese patent "CN118635787B An Ultrasonic Welding Fixture" consists of a base plate, a module frame support plate, and an upper pressure plate from bottom to top. It is used to press the side pressure components of the HPD module frame. The upper pressure plate, module frame support plate, and base plate are detachably connected by detachable connectors. The base plate has a negative pressure groove on its surface, and a guide hole communicating with the negative pressure groove is provided on its side wall. The module frame support plate has mounting holes into which the welding end of the HPD module frame can extend. Positioning pins are spaced circumferentially along the mounting holes on the surface of the module frame support plate. Welding grooves are provided on opposite sides of the upper pressure plate, with the bottom of the welding grooves communicating with the mounting holes. This ultrasonic welding fixture design solves the problem of existing HPD module frames being fixed using clamps, which have fewer fixing surfaces, are prone to loosening during welding, and cannot guarantee the welding effect between the HPD module frame and the chip.

[0004] Most mainstream electrical control cabinet frame welding and positioning equipment on the market adopts an integrated design architecture. To ensure a stable connection between components, bolts or welding are usually used for fixing. This lacks a flexible adjustment mechanism and makes it difficult to make precise and targeted adjustments according to the welding angle required for different metal frame poles. It can only meet the welding positioning needs of specific angles. Once it is necessary to weld metal frame poles at other angles, the equipment cannot achieve effective positioning. The welding operation can only be completed by the staff manually supporting the metal frame poles, which greatly limits the application scope and practicality of the equipment. Summary of the Invention

[0005] This invention relates to an electrical control cabinet frame welding device, which solves the problem that existing electrical control cabinet frame welding and positioning devices mostly adopt an integrated design. In order to ensure the firmness of the connection, the components are usually fixed by bolts or welding. It is difficult to make targeted adjustments according to the different welding angles required by the metal frame poles. They can only meet the welding and positioning requirements of specific angles. When welding metal frame poles at other angles, effective positioning cannot be achieved, and workers need to manually support the metal frame poles, which limits the application.

[0006] In a first aspect, the present invention provides an electrical control cabinet frame welding device, specifically comprising: a top connecting plate, a vertical connecting plate, a U-shaped connector, a lower connecting arm plate, an upper connecting arm plate, a force-bearing rotating shaft, a helical screw, a lifting support frame, a vertical screw, and a limiting clamping assembly; the top connecting plate is connected to the end of the vertical connecting plate, and a U-shaped connector is installed at the connection between the top connecting plate and the vertical connecting plate; the lower connecting arm plate is connected inside the vertical connecting plate, and the upper connecting arm plate is connected inside the top connecting plate, with a force-bearing rotating shaft connected to the lower connecting arm plate; a helical screw is connected inside the force-bearing rotating shaft, with the end of the helical screw connected to the U-shaped connector; a lifting support frame and a vertical screw are connected inside the top connecting plate, with the vertical screw connected to the lifting support frame; two limiting clamping assemblies are provided, one of which is fixedly installed outside the vertical connecting plate, and the other is fixedly installed on the top of the lifting support frame.

[0007] Furthermore, the limiting clamping assembly consists of a U-shaped fixed clamp, a U-shaped movable clamp, a force-bearing tie rod, a movable clamping plate, and a tightening screw. A guide rod is provided on the outside of the U-shaped fixed clamp, and a guide hole is provided on the outside of the U-shaped movable clamp. The guide rod slides through the guide hole, and the sliding cooperation between the guide rod and the guide hole achieves the effect of guiding the movement of the U-shaped movable clamp.

[0008] Furthermore, the movable clamping plate is slidably connected to the U-shaped movable clamping member. The U-shaped movable clamping member has a movable hole on its outside, and the movable clamping plate has a slider on its outside. The slider is slidably connected to the movable hole. The slider and the movable hole slide together to guide the movement of the movable clamping plate.

[0009] Furthermore, the force-bearing tie rod is rotatably connected to the U-shaped moving clamp, and the U-shaped fixed clamp has a docking notch on its outside, with the end of the force-bearing tie rod connected to the docking notch.

[0010] Furthermore, the U-shaped movable clamp has a screw hole C inside, and a tensioning screw is threaded into the screw hole C. The end of the tensioning screw is rotatably connected to the movable clamping plate. When the limiting clamping assembly is installed outside the metal frame rod to be welded, the force-bearing pull rod is rotated to move the force-bearing pull rod into the mating notch, and the tensioning screw is rotated. The tensioning screw drives the movable clamping plate to move outward. The force-bearing pull rod applies tension to the U-shaped fixed clamp, so that the U-shaped fixed clamp and the movable clamping plate are in close contact with the opposite sides of the metal frame rod, thereby achieving the clamping and fixing effect.

[0011] Furthermore, the top connecting plate is rotatably connected to the vertical connecting plate, the U-shaped connector is rotatably connected to both the top and vertical connecting plates, the lower connecting arm plate is rotatably connected to the vertical connecting plate, the upper connecting arm plate is rotatably connected to the top connecting plate, and the force-bearing rotating shaft is rotatably connected to both the lower and upper connecting arm plates.

[0012] Furthermore, the force-bearing rotating shaft is provided with a screw hole B inside, and the inclined screw is rotatably connected in the screw hole B. The end of the inclined screw is rotatably connected to the U-shaped connector. According to the different welding angles of different metal frame rods in the electrical control cabinet frame, the inclined screw can be rotated to drive the top connecting plate and the vertical connecting plate to rotate and adjust, thereby changing the angle of the two limit clamping components and thus changing the welding angle of the two metal frame rods.

[0013] Furthermore, the top connecting plate is provided with a vertical sliding hole, and the lifting support frame is slidably connected in the vertical sliding hole.

[0014] Furthermore, the top connecting plate is provided with a screw hole A, and the vertical screw is rotatably connected to the lifting support frame. The vertical screw is threaded into the screw hole A, and the vertical sliding hole plays a guiding role in the movement of the lifting support frame. By rotating the vertical screw, the vertical screw drives the lifting support frame to move up and down, and one of the limiting clamping components is moved up and down for fine adjustment, thereby driving the metal frame rod to move up and down for fine adjustment, so as to achieve precise docking between the two metal frame rods.

[0015] This invention provides an electrical control cabinet frame welding device, which has the following beneficial effects: In use, the guide rod and guide hole employ a sliding fit mechanism, which provides precise guidance for the movement of the U-shaped moving clamp, ensuring a stable and reliable motion trajectory. Simultaneously, the sliding fit between the slider and the movable hole creates a good guiding system for the movement of the movable clamping plate, ensuring smooth and accurate movement. When the limiting clamping assembly needs to be installed on the outside of the metal frame to be welded, the operator only needs to rotate the force-bearing pull rod to move it smoothly into the mating notch, and then rotate the tension screw. Under the transmission action of the screw, the movable clamping plate will move outward, and the force-bearing pull rod will apply a pulling force to the U-shaped fixed clamp, causing the U-shaped fixed clamping plate and the movable clamping plate to fit tightly against each other from opposite sides of the metal frame, thereby achieving a stable clamping and fixing of the metal frame. This not only effectively ensures the firmness of the connection between the limiting clamping assembly and the metal frame, but also makes the operation simple and easy, greatly improving work efficiency.

[0016] Furthermore, during the assembly of the electrical control cabinet frame, the welding angles required for different metal frame rods can be flexibly adjusted by rotating the inclined screw. Rotating the inclined screw can drive the top connecting plate and the vertical connecting plate to rotate together, thereby driving the two limit clamping components to change their angles synchronously. Ultimately, this achieves precise adjustment of the welding angle of the metal frame rods, which can efficiently meet the positioning requirements of diverse angle welding and significantly improve the adaptability of the equipment and the flexibility of the process.

[0017] In addition, the vertical sliding hole can provide precise guidance for the movement of the lifting support frame. In actual operation, by rotating the vertical screw, the lifting support frame can be driven to move up and down in a predetermined direction, thereby achieving fine up and down adjustment of one of the limit clamping components. This will drive the clamped metal frame rod to move up and down synchronously, ultimately achieving precise docking between the two metal frame rods. This effectively ensures the welding quality of the docking parts of the two metal frame rods and ensures that the welding effect meets high standards.

A guide rod 10011 is provided on the outside of the U-shaped fixed clamp 1001, and a guide hole 10021 is provided on the outside of the U-shaped movable clamp 1002. The guide rod 10011 slides through the guide hole 10021. The guide rod 10011 and the guide hole 10021... The sliding engagement serves to guide the movement of the U-shaped movable clamp 1002.

[0025] In this embodiment, the force-bearing tie rod 1003 is rotatably connected to the U-shaped movable clamp 1002. The U-shaped fixed clamp 1001 is provided with a docking notch 10012 on the outside. The end of the force-bearing tie rod 1003 is connected to the docking notch 10012. The U-shaped movable clamp 1002 is provided with a screw hole C10023 inside. The tensioning screw 1005 is threadedly connected to the screw hole C10023.

By adopting the above technical solution, the inclined screw 7 can be rotated according to the different welding angles of different metal frame rods in the electrical control cabinet frame. The inclined screw 7 drives the top connecting plate 1 and the vertical connecting plate 2 to rotate and adjust, thereby changing the angle of the two limit clamping components 10, thus changing the welding angle of the two metal frame rods. This better meets the welding positioning requirements of metal frame rods with different angles and has extremely strong adaptability.

[0028] The working principle of this embodiment is as follows: First, when the limiting clamping assembly 10 is installed on the outside of the metal frame rod to be welded, the force-bearing tie rod 1003 is rotated, causing the force-bearing tie rod 1003 to move into the mating notch 10012.

Next, according to the different metals in the electrical control cabinet frame... Depending on the welding angle of the support rods, rotating the inclined screw 7 causes the top connecting plate 1 and the vertical connecting plate 2 to rotate and adjust, changing the angle of the two limiting clamping components 10, thereby changing the welding angle of the two metal support rods and better meeting the welding positioning requirements of metal support rods with different angles. The vertical sliding hole 101 serves as a guide for the movement of the lifting support frame 8. By rotating the vertical screw 9, the vertical screw 9 drives the lifting support frame 8 to move up and down, and performs fine-tuning of the up and down movement of one of the limiting clamping components 10, thereby driving the metal support rod to perform fine-tuning of the up and down movement, achieving precise docking between the two metal support rods and ensuring the welding effect of the docking part of the two metal support rods.
